selftests: net: lib: Add a couple autodefer helpers

Browse Source 
Alongside the helper ip_link_set_up(), one to set the link down will be
useful as well. Add a helper to determine the link state as well,
ip_link_is_up(), and use it to short-circuit any changes if the state is
already the desired one.

Furthermore, add a helper bridge_vlan_add().
